Since 1 pound is $3.09, 4.5 pounds will be:
It says to round to nearest hundredth, so your answer is $13.91.
We have the sum of cubes identity
and observing that 1 + 4 = 2 + 3, we have
and
Then
Alternatively, we have the well-known sum of cubes formula
The sum under the square root is this sum with 
. Then
and so the square root again reduces to 15.
None of these couples are solutions, (11, 3)(11, 3); (−1, −6)(−1, −6); (−3, 3)(−3, 3); <span>(7, 0). Perhaps the choice of answer are insufficient. we can add (1, 48) the couple (7, 0) and (7, 0)(1, 48) is a true answer, why? because it verifies the equation.</span>
Making a triangle with line segment AC as the hypotenuse, we see the two legs are 6 and 8 units. Using the Pythagorean theorem, 6^2=36 and 8^2=64. 36+64=100. The square root of 100 is 10, so the length of AC is 10 units. Please give me brainiest. Have a great day.
Omg i can help you because I was having trouble with the same thing! so the Total Surface Area= Ph+2B meaning you have to find the P=perimeter Lx2+Wx2, then the height, then base. the lateral area is Ph+B :)!!
